“Bender,” my nickname for a male Gray Petaltail dragonfly (Tachopteryx thoreyi) with a malformed abdomen, is featured in the following set of annotated photos.
All male dragonflies have three terminal appendages, collectively called “claspers,” that are used to grab and hold female dragonflies during mating: an upper pair of cerci (“superior appendages”) and a lower unpaired epiproct (“inferior appendage”).
Gray Petaltail males have “indented” hind wings, as shown in the last photo.
